Answer:

y = (x - 7)^(1/3)

Step-by-step explanation:

Notice that f(x) is a monotonically increasing function (so it has an inverse along the domain \mathbb{R}\rightarrow \mathbb{R}.

To find the inverse, we interchange the variables and solve for y.

So interchanging the variables gives us:

x = y^3 + 7.

We then solve for y, giving us:

x - 7 = y^3

y = (x - 7)^(1/3).

<u><em>Seventy-seven is a composite number. </em></u>

Because you had to divide by eleven or seven. Then you can multiply by seven or eleven its equal to seventy-seven.

77/11=7

11*7=77

77/7=11

7*11=77

Final answer: \boxed{=77}

Answer:

Yes

Step-by-step explanation:

You can conclude that ΔGHI is congruent to ΔKJI, because you can see/interpret that there all the angles are congruent with one another, like with vertical angles (∠GIH and ∠KIJ) and alternate interior angles (∠H and ∠J, ∠G and ∠K).

We also know that we have two congruent sides, since it provides the information that line GK bisects line HJ, meaning that they have been split evenly (they have been split, with even/same lengths).

<u><em>So now we have three congruent angles, and two congruent sides. This is enough to prove that ΔGHI is congruent to ΔKJI,</em></u>

Enrique left the study group traveling 20 mph. Then, 2 hours later, Tevin left traveling the same direction at 28 mph. How long
nadya68 [22]

Answer:

After 7 hours Tevin will catch Enrique

Step-by-step explanation:

We have given speed of Enrique is 20 mph

Tevin left traveling after 2 hours of Enrique

Speed of Tevin  is 28 mph

When Tevin catches  Enrique will cover same distance

Let  Enrique is traveling for t hours

Then Tevin will travel for t-2 hours

We know that distance = speed × time

So 20\times t=28\times (t-2)

20t=28t-56

8t=56

t = 7 hours

So after 7 hours Tevin will catch Enrique
